git-log produces no output
When $PAGER is set to 'less -i', we used to fail because we assumed the $PAGER is a command and simply exec'ed it. Try exec first, and then run it through shell if it fails. This allows even funkier PAGERs like these ;-): PAGER='sed -e "s/^/`date`: /" | more' PAGER='contrib/colordiff.perl | less -RS' Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
